The HLG 300 V2 RSpec LED Grow Light from Horticulture Lighting Group is a high-quality American-made light that only draws 270 watts but gives you an output equal to a 600 watt HID light.

Each HLG-300 V2 uses two of HLG's custom-designed full-spectrum high efficiency white light quantum boards with Samsung LM301H and Deep Red LED 660nm. The light is dimmable from 90 to 270 watts.

This light is excellent for flowering and for the full grow cycle. If you need a light specifically for vegging, the HLG 300L V2 BSpec is the one you want.
